FIELD: gas production.
SUBSTANCE: group of inventions relates to internal elements used in fluidized beds, in which solid particles and fluid move in opposite directions. The packing system for the fluidized bed of solid particles and gas contains at least one generatrix, and the generatrix contains a plurality of flat plates. Each plate has a plane for directing gas-solid flow along said plane, and the plates are arranged in alternating intersecting planes to provide a plurality of open spaces between or near the alternating intersecting plates. Said planes of alternating intersecting plates provide at least two different gas-solid flow directions for a given generatrix. One plate contains at least one gap that separates the plate into at least a first separated plate section and at least a second separated plate section. Each separated plate section has a plane. Said gap provides an area for passage into open spaces. The plane of the second section of the plate is offset relative to the plane parallel to the plane of the first section of the plate, and is placed above or below the first section of the plate. The order of the plates allows the movement of suspended solids in different directions within the same layer of the packed system to enhance the cross-mixing of gas and catalyst in all directions, and reduces the likelihood of gas and catalyst bypass movement. The plate layout has discontinuities that minimize phase separation around the plate. The location and size of the plates are designed to facilitate close contact between the two phases and to ensure efficient mass transfer of material entrained in solids to the gas phase. The plate arrangement prevents overgrowth of bubbles and formation of channels that reduce the plane area for mass transfer. Also claimed is a fluidized bed of solid particles and gas and a method for increasing mass transfer between gas and solid particles.
EFFECT: group of inventions improves mass transfer by increasing the plane area, increasing the intensity of mixing, as well as increasing the space for the movement of gaseous and solid phases in the packed system, reducing the weight of the structure, which makes it lighter and less expensive.
